Ingredients

• 1½ pounds beef tenderloin tips
• 4 tablespoons unsalted butter, cut into small pieces
• 1 packet dry onion soup mix, about 1 ounce
• 1 teaspoon garlic powder
• ½ teaspoon black pepper

Instructions

1. Preheat the oven to 350°F (175°C). Prepare a 2-quart glass casserole dish.
2. Add the raw beef tenderloin tips to the casserole dish and spread them into an even layer.
3. Sprinkle the dry onion soup mix evenly over the beef.
4. Add the garlic powder and black pepper over the top.
5. Scatter the butter pieces across the seasoned beef tips.
6. Cover the casserole dish tightly with aluminum foil to keep the beef tender and juicy.
7. Bake for 35 to 45 minutes, or until the beef reaches your preferred doneness. For medium beef, use a food thermometer and check that the thickest pieces reach at least 145°F (63°C).
8. Remove the dish from the oven and let it rest, covered, for 5 to 10 minutes.
9. Stir the beef gently in the buttery onion garlic juices, then serve hot.

Serving Suggestions

These juicy oven beef tips are delicious served over creamy mashed potatoes, buttered egg noodles, fluffy white rice, or roasted baby potatoes. Add steamed green beans, sweet corn, carrots, or a fresh green salad for a balanced family dinner.

Crusty bread or warm dinner rolls are also perfect for soaking up the savory onion butter sauce.

Tips and Variations

For a thicker gravy, mix 1 tablespoon cornstarch with 2 tablespoons cold water. Stir it into the hot pan juices after baking, then return the uncovered casserole dish to the oven for 5 to 10 minutes.

For extra flavor, add sliced mushrooms before baking. Mushrooms pair beautifully with the onion garlic butter sauce and make this easy beef tenderloin tips recipe even more filling.

If you prefer a saucier dish, add ¼ cup beef broth before covering and baking. This creates more savory juices for serving over rice, potatoes, or noodles.
